US 12,758,079 B2 · Dishwasher and method of controlling dishwasher

Abstract

Disclosed herein are a dishwasher and a method of controlling the dishwasher. The dishwasher includes: a first sensor configured to detect whether a push bar for selectively opening and closing a door has deviated from a first reference point; a second sensor configured to detect changes in the signal attributable to the movement of the push bar based on a second reference point that is different from the first reference point; a third sensor configured to detect changes in the signal attributable to the movement of a movable member, to which the push bar can be coupled, based on a third reference point that is different from the second reference point; and a control unit configured to determine the opened/closed state of the door based on the detection result of at least one of the first, second, and third sensors.

A door opening device for a dishwasher, the door opening device being provided on one side of a main body of the dishwasher and performing opening of a door with respect to the main body, the door opening device comprising:

a case fixed to the main body;
a movable member disposed inside the case to be slidably movable with respect to the case;
a latch unit including at least one latch rotatably mounted on at least one fixing shaft inside the movable member;
and
a latch guide member disposed on the movable member to be slidably movable with respect to the movable member;
wherein the latch guide member guides the latch unit so that the at least one latch is rotated as the latch guide member slides, and
wherein, in the latch guide member, at least one fixing shaft receiving depression extending in forward and rearward directions is formed at a location corresponding to the at least one fixing shaft, and the at least one fixing shaft is inserted into the at least one fixing shaft receiving depression.
